Steps to Reassemble Rear Drum Brakes Efficiently and Effectively

How to Put Rear Drum Brakes Back Together

When it comes to maintaining your vehicle, understanding the workings of your drum brakes is essential. Drum brakes are common in many vehicles, especially older models and in their rear systems. If you’ve recently replaced or serviced your drum brakes, knowing how to reassemble them correctly is crucial for effective brake performance and safety. In this guide, we’ll walk you through the steps of putting rear drum brakes back together.

Tools and Materials Needed

Before you start, ensure you have the right tools and materials for the job - Brake cleaner - Brake grease - A set of socket wrenches - Screwdrivers (flathead and Phillips) - Drum brake spring tool (optional but recommended) - New brake shoes (if replacing) - New wheel cylinders (if necessary) - A clean cloth

Step 1 Remove the Brake Drum

If you haven't already, remove the wheel and then the brake drum. You'll want to inspect the brake drum for any scoring or damage. If it’s too worn, it might need to be replaced. Clean the inside of the drum with brake cleaner to remove any dust and debris.

Step 2 Inspect Components

Before reassembling, inspect the components involved. Look at the brake shoes, springs, and wheel cylinders; replace any that are worn or damaged. Check the condition of the backing plate for rust or damage and clean it if necessary.

Step 3 Prepare the New Brake Shoes

If you are installing new brake shoes, compare them to the old ones to ensure a proper fit. Apply a light coat of brake grease to the backing plate where the shoes will rest. This will help them move smoothly.

Step 4 Install the New Brake Shoes

Begin the assembly by positioning the new brake shoes onto the backing plate. Make sure that the shoes are placed correctly; the shoe with the smaller lining is usually installed at the rear. Align each shoe with the corresponding holes and use any retaining clips or bolts as necessary to secure them to the backing plate.

Step 5 Attach the Wheel Cylinder

If you’re replacing the wheel cylinder, now's the time to install it. It is typically positioned at the top of the brake assembly. Attach the cylinder to the backing plate using bolts. Be sure to connect the brake lines properly and check for any leaks after reassembly.

Step 6 Position the Springs and Hold-Down Clips

Now, it’s time to install the hold-down springs and clips. These components hold the brake shoes in place and ensure they function correctly. Use a brake spring tool to stretch and position these springs safely without risking injury.

Next, install the return springs that connect the bottom of the brake shoes. This helps return the shoes to their resting position after the brake pedal is released. Make sure each spring is firmly seated to avoid any issues during operation.

Step 7 Reinstall the Brake Drum

Once all components are secured and checked, it’s time to reinstall the brake drum. Slide the drum back onto the hub, ensuring that it rotates freely. If it is too tight, you may need to adjust the shoes or the adjusting wheel located on the backing plate.

Step 8 Test Your Work

Before putting the wheel back on, pump the brake pedal a few times to ensure that the shoes seat correctly against the drum. Check for any unusual noises or resistance that could indicate a problem.

Conclusion

Reassembling rear drum brakes may seem daunting, but with careful attention to detail and the right tools, it can be accomplished successfully. Always make sure to prioritize safety by wearing proper protective gear and following manufacturer specifications. If you feel unsure about any steps or notice any issues during your reassembly, consult a professional mechanic. Well-maintained brakes are vital not just for the performance of your vehicle but for your safety on the road.
